Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor joint device for covering joints of floors of left and right buildings built through joints.

[0002]

2. Description of the Related Art A conventional floor joint device is one concave portion formed on the joint-side floor surface of one building on the opposite joint side with an inclined surface, and the other building corresponding to the one concave portion. Joint plate supporting concave portion formed on the floor surface of the joint portion side, and a rear end portion movably up and down in the joint plate supporting concave portion, and a tip end portion supported so as to cover the one concave portion. The joint plate includes a joint plate having an inclined surface, and a support tool that supports the rear end of the joint plate in the joint plate supporting recess so as to be vertically movable.

[0003]

In the conventional floor joint device, the left and right buildings sway due to an earthquake or the like, and when the joint portion becomes narrow, the tip end of the joint plate having the inclined surface is formed on the inclined surface of one concave portion. Is slid and moved so as to project in an inclined state on one floor surface. Therefore, there is a drawback that the joint plate is dangerous because the tip portion of the joint plate projects upward from one of the floor surfaces in an inclined state.

In view of the above-mentioned conventional drawbacks, the present invention has been made.
It is an object of the present invention to provide a floor joint device that can prevent a danger by allowing the joint plate to move in a substantially horizontal state even when the joint portion becomes narrow.

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in view of the accompanying drawings. However, the drawings are only for explanation and do not limit the technical scope of the present invention.

[0006]

In order to achieve the above object, the present invention provides a floor surface of one of the left and right buildings built via a joint portion so as to open to the joint portion. A concave portion, the other concave portion formed on the other floor surface of the left and right buildings, at least two or more guide cylinders formed in the other concave portion, one end portion of which covers the one concave portion, and A joint plate whose end portion is attached so as to cover the other concave portion, and a joint plate slide moving mechanism that slides one end portion of the joint plate onto one floor surface when the joint portion becomes narrow due to an earthquake or the like, Guide pins fixed to the bottom surface near the other end of the joint plate and slidably inserted in the guide cylinders, and one end fixed to the bottom surface near the other end of the joint plate are inclined surfaces. A raised plate and one end thereof is pivotally supported on the joint side frame of the other building, and the other end is slidable or pivotally supported on a rail attached to the joint side frame of the one building. Further, when the joint portion becomes narrow due to an earthquake or the like, it comes into contact with the inclined surface of the lift plate, and the lift mechanism that pushes the lift plate upward constitutes a floor joint device.
